Add code option to Sprockets Render

[NGMarmaduke]

This enables additional code to be added to the Exec JS context when initialised.

Our app is consuming assets generated via Sprockets and Webpack, this option allows the Webpacked assets to injected along side the Sprockets assets for use in the ExecJS runtime.

Very nice! For user code, does this option go in server_render_options, for example:

config.react.server_renderer_options = {
  code: File.read(webpack_bundle),
  # ...
}

?

It could certainly be set via the server_render_options in application.rb, for our app we already use a custom render to enable i18n:

class JsRenderer < SprocketsRenderer
  def initialize(options = {})
    options[:code] = webpack_assets
    super(options)
  end

  def before_render(component_name, props, prerender_options)
    super + set_i18n_js
  end

  def after_render(component_name, props, prerender_options)
    super + 'alt.recycle();'
  end

  private

  def set_i18n_js
    [i81n_js, moment_js].join
  end

  def i81n_js
    "I18n.locale = '#{ I18n.locale }';"
  end

  def moment_js
    "moment.locale(I18n.locale);"
  end

  def webpack_assets
    webpack_manifest.javascript_assets.map do |filename|
      webpack_manifest.find_asset(filename)
    end.join
  end

  def webpack_manifest
    WebpackAssets.manifest
  end
end
